I have a few questions:
44. How is this any different from [unparseable or potentially dangerous latex formula]?
46, 48: Moment of inertia questions. I still don't know how to use moment of inertia, so I will study them. A brief explanation would be appreciated.
53. How do you work out that circuit? I did a circuit like that before, but I have forgotten how to break down weird circuits like that.
55. Time dilation: initially, I got Mary was older by 1.41 years, and I realized I had flipped something. Now, I get that Mary is older by about 1.78 years. Help please?
60. Thermal expansion is always uniform?
